How to Measure the Impact of Nutrition

We all want to feel better, have more energy, and stay healthy in the long run. And most of us know that nutrition plays a big role in that. But here’s the tricky part: how do you really know if your nutrition is working?

You might be eating more greens, taking your supplements, and avoiding processed foods, but how do you measure the impact? How do you know what’s actually helping, and what’s just hype?

In this post, we’ll walk you through the different ways to track how nutrition affects your health, from simple daily observations to more detailed blood tests.

Whether you’re just starting your wellness journey or looking to fine-tune it, here’s how to make your nutrition more personal, measurable, and effective.

1. Listen to Your Body First

Before we look at any numbers or tests, start with the basics: how do you feel?

Nutrition isn’t just about what’s on your plate, it’s about how your body responds. Some questions to ask yourself:

• Do I have stable energy throughout the day?

• How’s my digestion, am I often bloated or sluggish?

• Do I sleep well and wake up feeling rested?

• How often do I get sick?

• Is my skin clear and healthy-looking?

• How’s my mood and focus?

Your body gives you feedback all the time. Tuning into these signals is one of the simplest and most powerful ways to measure your health.

2. Blood Tests: A Clearer Look Inside

If you want more objective insights, blood tests are a great tool. They help you see what’s happening on a deeper level, and where your body might need support.

Some helpful markers to track:

• Vitamin D: Essential for immunity, energy, and mood and commonly low.

• Vitamin B12 & Folate (B9): Needed for energy, brain function, and red blood cells.

• Ferritin (Iron Stores): Low levels can lead to tiredness and poor concentration.

• CRP (C-reactive protein): A general marker for inflammation.

• Omega-3 Index: Measures your levels of healthy fats for brain and heart health.

• HbA1c: Shows your average blood sugar over the last 2–3 months.

• Zinc & Magnesium: Often low during stress and crucial for recovery and calm.

A yearly check-up with these markers can be a great way to monitor progress and make sure you’re getting what you need, especially if you’ve changed your diet or started taking supplements.

3. Track Progress in Daily Life

It’s not all about lab results. Many signs of improved nutrition show up in everyday life. 

Try tracking these:

• Energy levels: Do you feel more energised and less dependent on coffee or sugar?

• Sleep quality: Are you falling asleep easier or waking up more refreshed?

• Digestion: Less bloating, more regular bowel movements, or improved comfort after meals.

• Skin and hair: Brighter skin, fewer breakouts, or stronger nails and hair.

• Mental clarity: Sharper focus and less “brain fog.”

• Mood: More balanced, less irritability or low moods.

• Exercise recovery: Less soreness, better endurance or strength.

You can keep a simple weekly journal or even rate each area on a 1–10 scale to see how things shift over time.

4. Gut Health = Nutrient Absorption

You could be eating the healthiest foods in the world, but if your gut isn’t working well, your body won’t absorb all those nutrients.

Signs of gut imbalance:

• Bloating, irregular digestion, or food sensitivities

• Skin issues (like acne or eczema)

• Low mood or anxiety

• Frequent illness or fatigue

Supporting gut health can improve how well your body uses the food you eat.

Try:

• A fibre-rich diet with whole foods

• Probiotics and fermented foods (like kefir or sauerkraut)

• Prebiotics (from foods like onions, leeks, and oats)

• Staying hydrated

• Managing stress, it impacts your digestion more than you might think!

5. When Supplements Make a Difference

Even with the best diet, some nutrients are hard to get consistently, especially if you have higher needs, a restricted diet, or gut issues.

Examples:

• Vitamin D3: Almost impossible to get enough from food alone, especially in winter.

• Vitamin B12: Hard to absorb and only found in animal products – a common issue for vegetarians, vegans, or people with digestive conditions.

• Magnesium: Often depleted by stress, poor soil quality, or common medications.

• Omega-3s: Found mainly in fatty fish, which many people eat too little of.

• Zinc & Selenium: Crucial for immunity, skin, and hormone balance — but easily missed.

In these cases, a high-quality supplement can help fill the gap. It’s not about taking everything, but about understanding what you need most and choosing wisely.

6. Every Body Is Different

This might be the most important point: nutrition is never one-size-fits-all. What works for your best friend might leave you feeling off.

We all have different metabolisms, lifestyles, genetics, stress levels, and gut microbiomes. That’s why tracking your personal experience - alongside data like blood work - gives you the best picture.

And remember: your needs may change. What helped last year might need tweaking this year. Nutrition isn’t static, it evolves with your body and your life.

Make Nutrition Work For You

Measuring the impact of your nutrition isn’t about being perfect, it’s about being curious. It’s about learning how your body works, what it needs, and how to support it in a way that feels sustainable.

Start with awareness. Use simple tracking methods. Ask your doctor about key tests. Tune into how you feel. And if needed, add smart supplements to fill in the gaps.

When you understand your body, it’s easier to take care of it, and feel your best every day.
